Lower Khazir River is crossing three mountains (Maqlub , Ain Al-Safra, and Makhmoore) and it is adjustment to the neotectonic activity by fold. During the study evaluate active tectonics by using DEM derived drainage network and geomorphic indices stream-length gradient (SL), basin asymmetry factor (AF), hypsometric integral (HI), valley floor width to valley height ratio (Vf), Basin shape (Bs) and mountain front sinuosity (Smf). Geomorphic indices are calculate (IRAT) in the study site. So I classified the IRAT index into very higher, higher, modern and lower active of tectonic. The value of very higher is in sub basin 1 and 18 , higher is in sub basin 6, 10, 14 and 17 , modern is in sub basin 2,3,4, 5 ,7 , 9 ,16 and 19; and lower is in sub basin 8,11,12,13 and 15. About 10.5% of the study area (about 29.87) km2): 21% (111.63 km2) to Class 2: 42% (312.59 km2) to Class 3 and 26.5% (133.75 km2) to Class 4. IRAT tends to be high along the fold and fault zone. Two different levels of the rock are found in the study site (middle hard and soft rock).
